Approx 3inch dia and 2.25inch high. It has a shallow concave base with very hard wear around the edge. The facets are not perfectly flat in execution and have a slight wavy edge to them, not perfectly geometrical. Four rows of 8 facets each plus top. Some facets have small corner chips but in pretty good overall condition. Possibly Bohemian or Czech?? Maybe something else completely. Can any body help me with this? Thanks.
